|What I thought was going to be a simple problem is getting to the point of defeating me so here goes.|
Computer connected using a USB LAN adapter was failing to load webpages and failing to update security programs etc. Things done so far:
Deleted cookies, temp files etc.
Checked settings in Internet Options/connections
ping 127.0.0.1 - ok
ping 126.96.36.199 - ok
ping www.google.com - cannot find
OK so figure it's a DNS problem.
reset tcp/ip using netsh int ip reset resetlog.txt
ran full scan with Kaspersky Rescue Disk, DrWeb, Malwarebytes & System Mechanic (the latter was the security program initially on there - since uninstalled as I thought it was the problem)
turned off Windows firewall, no other firewalls installed
Checked the HOSTS file - nothing apart from 127.0.0.1 local host
Still no joy, I can access webpages with their ip address, but not with the www address.
Same on 3 different browsers.
I get an Error 105 (net::ERR_NAME_NOT_RESOLVED) message which points towards DNS servers so I've tried using different DNS servers in the network adapters settings, still no joy.
The problem still occurs on two different ISPs.
I think that was about all anyway next step is a reinstall, but I don't particularly want to do this as it's an oldish computer with a lot of data to backup so any other suggestions greatly appreciated.
